Question 2 - Create Aggregate/summary Route

Question 1

Create a suitable aggregate address and subnet mask for the following
routes: 196.199.65.0
196.199.66.0 196.199.67.0 196.199.68.0
Be sure to show all your working.

Answer 1

196. 199.65.0
     196.199.66.0
197. 199.67.0
198. 199.68.0

Convert to binary

11000100. 11000111.01000001.0
11000101. 11000111.01000010.0
11000102. 11000111.01000011.0
11000103. 11000111.01000100.0

Count matching bits to get subnet mask = /21

196.199.64.0
